Click Mode Operating Instructions 8-7
8.7.3 Determination of N
As required by the standard, N may be determined either by counting the
clicks, or by counting the switching operations.
Select
Clicks
if N has to be calculated on the number of clicks, or select
Sw.Op. current to determine N on the number of switching operations,
going up and down the list of the available options in terms of switched
current: 10mA; 20 mA; 50 mA; 100mA; 200mA; 500mA; 1A; 2A and 5A.
The current threshold value must be chosen in relation to the DUT declared
consumption.
The internal LISN is able to autonomously measure the mains current
drawn by the Device Under Test, when you need to count the
switching operations.
8.7.4 Factor f
The applicable standard may require a certain factor f to be used to
calculate the click rate N. For example, table A2 of the CISPR14 gives the
factor f for several products.
This factor depends on the nature of the EUT and shall be entered by the
User in the normal way.
8.7.5 Stop on Fail
The Click test may be rather long, as the observation time and EUT cycle
can take as long as 120 minutes.
In order to save time and increase productivity, the PMM ER9000 can stop
the test as soon as a fail condition is achieved.
Two options are therefore available: stop immediately as the fail condition
occurs (Right away) or anyway at the End of Step.
Please select the desired option.
8.7.6 Line
When using a PMM LISN, it’s possible to select the Line on which to
perform the test through the Setup Menu, just selecting the model and the
specific desired line.
In case a 3rd party LISN would be used, just leave “NONE” in the menu.
